Only if that is a little c with the word universal in front of it and not referring to the church led by the Bishop of Rome.
I've never gotten upset. We know that Scripture is the only thing GIVEN TO US for instruction that can be verified. We can't verify oral tradition. We can't verify dreams, prophecies, etc. But we can verify what Scripture says.
Is Sola Scriptura in the Bible?
"Only if that is a little c with the word universal in front of it and not referring to the church led by the Bishop of Rome."
The Catholic Church existed LONG before CAPITAL LETTERS existed, Its always been the one and only.
"We know that Scripture is the only thing GIVEN TO US for instruction that can be verified."
Not according to scripture. It says when someone sins in error you take it to the church.
We see Paul do this:
2 Corinthians 13
1This is the third time I am coming to you. EVERY FACT IS TO BE CONFIRMED BY THE TESTIMONY OF TW

R THREE WITNESSES.
2I have previously said when present the second time, and though now absent I say in advance to those who have sinned in the past and to all the rest
as well, that if I come again I will not spare
anyone, 3since you are seeking for proof of the Christ who speaks in me, and who is not weak toward you, but mighty in you.
4For indeed He was crucified because of weakness, yet He lives because of the power of God. For we also are weak in Him, yet we will live with Him because of the power of God
directed toward you.
5Test yourselves
to see if you are in the faith; examine yourselves! Or do you not recognize this about yourselves, that Jesus Christ is in you—unless indeed you fail the test?
6But I trust that you will realize that we ourselves do not fail the test.
7Now we pray to God that you do no wrong; not that we ourselves may appear approved, but that you may do what is right, even though we may appear unapproved.
8For we can do nothing against the truth, but
only for the truth.
9For we rejoice when we ourselves are weak but you are strong; this we also pray for, that you be made complete.
10For this reason I am writing these things while absent, so that when present I
need not use severity, in accordance with the authority which the Lord gave me for building up and not for tearing down.
Matthew 18
15“If your brother sins, go and show him his fault in private; if he listens to you, you have won your brother.
16“But if he does not listen
to you, take one or two more with you, so that BY THE MOUTH OF TW

R THREE WITNESSES EVERY FACT MAY BE CONFIRMED.
17“If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
18“Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven.
"Is Sola Scriptura in the Bible?"
(No, and yes.) The Bible does not have specific text that suggests that the Bible alone is our final authority in all matters of faith and practice. --RC Sproul
This is going to bite you in one end or the other. Your teaching is admitted not biblical. Trying to spin it as ITS BIBLICAL but its not in the BIBLE.
Seriously? Its not in the bible = its biblical? He could not even find a bible verse implicitly teaching this.
Isn't the whole point of it is so when you hear someone swear up and down this is a teaching, you flip through a bible and say WELL its not written in the scriptures.
No one suggested this was the teaching for 1500 years.
"We know that Scripture is the only thing GIVEN TO US for instruction that can be verified."
Well its been verified Sola Scriptura is not in the scriptures and its been verified that scripture is NOT the only thing given to us for instruction.
